I had a chance to chat to a CSM on a longer flight about this - and they didn't think spirits would be coming back anytime soon.
Part of the reasoning was that storage space at the front of the plane was at a premium previously, with all galley storage assigned to what they need to carry. (In fact at he beginning of the century we had seen flight storage start to creep out of the galley and into the overhead bins above the front rows, thankfully on newer B737s this has been pared back to one bin on the starboard side.)
Anyway, the conundrum now is they need to carry PPE, including masks and wipes for passengers, and with all usable storage space already assigned - something had to give, and at this stage that means spirits can't fit
